I have a Dell XPS 8100 (from 2010) with same chipset and upgrading from i5 650 to new i7 870 allowed me to use higher graphics settings for my GTX 1060 which now seems to be the limiting factor. In some games the GPU goes as much as 100% while 60% max CPU. X3470 appears to be the same chip other than adding ECC RAM support (which you do not have anyway) and more expensive unless you find a cheap used one. I also upgraded my RAM from 8 GB 1066 to 16 GB (4x4GB) DDR3 1333 RAM. But yours only has 2 slots and 4 GB is max supported per slot.
has anyone tried xeon x3470 on chipser H 57 on dell inspiron 580 pre-built pc? Does it work?
